Good for a twenty gallon?

wll if you decide to get the damselfish put them in the last so the other tank mates have already established them self because damselfish can get pretty aggressive. Well good luck to you.
 
In a 20, you'll have room for 1-4 fish in my opinion. All depends on which ones you get. I'd not do damsels personally, too aggressive and will limit what else you can keep. I'd not do the mandarian either, although they are small they need a larger mature tank to supply them with enough pods. Assessors, clowns, cardinals, gobies, dartfish would all make good candidates. So would shrimp and other inverts. Some might go a whole other route and do a species tank with either one scorpionfish or a seahorse/pipefish tank. Depends on what appeals to you.
 
well...am gonna be honest and say 3 fish maximum in a 20 gal tank, and small fish at that....by the time you have any rock and equipment in there, you are talking very little room indeed....

But, this is of course, my own opinion...
